I sat on the Steering Committee Election Tabulation Committee (SCETC) for the 2007 National Green Party Convention - and I'd like to share the process by which we secure and count votes for internal positions.
Eight candidates ran for the Steering Committee, which had four seats open, and people ran for Secretary. (There were also several write-ins.)
After the Ballots where cast, they were escorted by five committee members, and four observers, to the tabulation room.
The committee split into two groups of two, with one floater who was called in occasionally to help decide questionable votes. Each team had up to 4 observers.
The votes were divided into two piles, and each team took turns tallying them and recorded the results.
Both master lists were compared to ensure they were identical; if discrepancies occurred the SCETC would retrieve the ballot which had been numbered and check the correct answer.
Finally, the votes were uploaded into a specially designed software for tabulations. (We Greens use a Single transferable vote system for these kinds of elections. It's complicated math and would take too long to be done by hand.)
The original ballots and master list where copied and the original and the copy each respectively sealed.
One ballot was so badly marked that it was near impossible to decide the intent, so two observers were sent to the plenary session to track down the voter. (The election was open, so each ballot had the name of the delegate on it.)
The ballot belonged to a delegate that had cast it as a proxy, so the delegate could not be found. But since the name of the delegate for whom it was cast was also on the ballot the SCETC ask the two observers to find a person that had the phone number of the delegate whose proxy it was. A delegate was found and the person was called and clearly identified the intent so even this ballot was counted.
It would be nice if in a much more important election like President of the USA the responsible parties would undertake the same effort to ensure that every vote counts
